ankoles [38]3 years ago
7 0

Answer:

Examples of biotic factors in an ecosystem are plants and animals

Examples of abiotic factors in an ecosystem include sunlight and type of soil

Explanation:

An ecosystem is a self-supporting unit composed of living and non living parts. Materials and energy flow within the ecosystem.

The ecosystem is composed of living and nonliving parts which affect each other in very significant ways.

The biotic factors of the ecosystem are the living factors such as plants and animals.

The abiotic factors are the nonliving factors of the ecosystem such as sunlight and type of soil.

The water-gas shift reaction plays a central role in the chemical methods for obtaining cleaner fuels from coal:CO(g) + H₂O(g) ⇄
lilavasa [31]

The reaction will proceed in the reverse direction in order to increase the concentrations of both CO and H2O and decrease that of CO2 and H2 until Q = K.

The reaction will proceed to the left

Step 1: The balanced equation

CO(g) + H2O(g) ⇌ CO2(g) + H2(g)

Step 2: Data given

Kp = 2.7

Number of moles of CO = 0.13 mol

Number of moles of H2O = 0.56 mol

Number of moles of CO2 = 0.62 mole

Number of moles of H2 = 0.61 mol

Volume = 2.0L

Step 3: Calculate Q

Pco = 0.13 / 1.92  P

Ph2o = 0.56 / 1.92 P

Pco2 = 0.62/1.92 P

Ph2 =0.61 / 1.92 P

Q =  [CO2][H2] / [CO][H2O] = 5.2

Q > Kp  The reaction will proceed to the left

The reaction will proceed in the reverse direction in order to increase the concentrations of both CO and H2O and decrease that of CO2 and H2 until Q = K.

To know more about concentrations of both CO and H2O

what is the electrical charge of the nucleus of an atom that has 12 protons and 12 neutrons and 12 electrons
ExtremeBDS [4]

Answer:

Neutral.

Explanation:

Protons have a positive charge. In this problem there are 12.

Electrons have a negative charge. In this problem there are 12.

Neutrons have a neutral charge that isn't relevant tot the overall charge, it can be ignored.

#protons - #e- = charge

12 - 12 = 0

The protons and electrons balance each other out, resulting in a 0 net charge. This means the atom has a neutral charge.

How many grams of mercury can be produced if 18.0 g of mercury (11) oxide decomposes?
NARA [144]

Answer:

18.0 g of mercury (11) oxide decomposes to produce 9.0 grams of mercury

Explanation:

Mercury oxide has molar mass of 216.6 g/ mol. It gas a molecular formula of HgO.

The decomposition of mercury oxide is given by the chemical equation below:

2HgO ----> 2Hg + O₂

2 moles of HgO decomposes to produce 1 mole of Hg

2 moles of HgO has a mass of 433.2 g

433.2 g of HgO produces 216.6 g of Hg

18.0 of HgO will produce 18 × 216.6/433.2 g of Hg = 9.0 g of Hg

Therefore, 18.0 g of mercury (11) oxide decomposes to produce 9.0 grams of mercury
